摘要
Abstract
The phenolic resin was modified by polyamide for improving the toughness of phenolic foam,and was foamed by chemical method. The effect of polyamide on the properties of phenolic resin and foam was studied with the analytical methods including DSC, gel-time,bending strength,and SEM. The results showed that the co-curing between polyamide and phenolic resin happened,the reactivity of phenolic resin decreased with the increasing of polyamide,the polyamide improved the toughness of phenolic foam effectively, the bending strength of phenolic foam presented the trend of up first and down second with the increasing of polyamide,and attained the most enhancing about 81% than the unmodified when the content is 10wt% ,the bubble structure of phenolic foam is improved from the SEM images by adding a little of polyamide, when adding 10wt% it is best and the bubble size is symmetrical in which the average diameter is about 400 μm.关键词
